[0019] The present invention has the following drawings: Figure 1 A system architecture diagram of an embodiment of the present invention; Figure 2 A display flow chart of an embodiment of the present invention; Figure 3 A user interface diagram of an embodiment of the present invention; Figure 4 A linkage interaction flow chart of an embodiment of the present invention. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] To make the objectives, advantages, and features of the present invention more obvious, the present invention will be further described in detail below with reference to the drawings and specific embodiments.

[0021] This embodiment designs a process for an electrical connector end face model display and linkage system. It is known that an electrical connector has multiple contact parts, and each contact part has a specific size and position. The purpose is to realize the recognition and data export functions through the system, which can display the graphical representation of these contact parts and allow users to highlight the corresponding graphical items by clicking on the entries in the table. Specifically, it includes the following steps: S1: Define an XML-formatted model file that details the key information of the end face profile and contacts of the electrical connector, including dimensions, coordinates, shape, etc. The model file is organized as <diagram>and <collection>Two main labels, where <collection>The label is used to store the shape and profile information of the contact, while <diagram>The label records the position distribution information of the contact and the contour shape. This structured data organization method facilitates subsequent parsing and processing.

[0022] S2: Image preprocessing. Before image recognition, the imported image is first preprocessed to improve the recognition accuracy. First, techniques such as Gaussian filtering or median filtering are used to remove noise in the image to ensure the accuracy of subsequent processing. Then, the contrast and brightness of the image are adjusted to make the pins and text more clearly visible. Finally, the image is converted into a black-and-white image to make it easier to identify edges and shapes.

[0023] S3: Use the image recognition technology that combines the Adaboost algorithm based on Haar features and the MESR algorithm with the Tesseract engine to automatically recognize the end-face diagram of the electrical connector and extract key information. Through the trained classifier, the system scans the image to identify possible pin areas. The features of each pin (such as position, size, and shape) are extracted and recorded, and interfering elements in the image are excluded. For example, the recognized contact 1 is located at position (100, 200) and has a size of 20x10. This step greatly improves the automation and accuracy of recognition, reduces manual intervention, and improves efficiency.

[0024] S4: While identifying the pins, the system also calls the MESR algorithm for text detection and combines it with the Tesseract engine for text recognition. Identify areas in the image that may contain text. Perform character recognition on the detected text areas and convert the text in the image into an editable text format.

[0025] S5: Use the C++ language and the Qt framework to develop a graphical interface, including the overall interface, the sample library building function interface, and the precise recognition function interface. These interfaces provide a window for users to interact with the system and also allow users to intuitively view and edit the detailed information of the electrical connector. Initialize QGraphicsView and QGraphicsScene objects and set the scene size to 800x600 pixels.

[0026] S6: Read the XML file through the XML parsing module, parse out the position and size information of the contact, extract the shape definition information and position distribution information, and map them to QGraphicsItem objects, and finally add them to QGraphicsScene for graphical display. For example, parse out the information of contact 1 and prepare to create a corresponding graphic item in the graphic scene.

[0027] S7: According to the parsed information, use QGraphicsEllipseItem to create an elliptical graphic item to represent the contact 1, and add it to the QGraphicsScene. Set its position to (100, 200) and set appropriate dimensions.

[0028] S8: Create a QTableWidget to display the detailed information of the contacts, such as ID, position, and dimensions. Connect a slot function to the signal for changing the current cell of the QTableWidget. When the user clicks on a row in the table, this slot function will be triggered. It will find the corresponding graphic item in the QGraphicsScene and change its color to highlight it.

[0029] S9: Implement basic interaction functions including zooming, panning, selecting, and editing model elements, allowing users to zoom and pan the scene by using the mouse wheel and dragging. Design the user interface, including a toolbar that provides zooming and panning buttons, and a menu option that allows users to adjust the display settings and model parameters as needed.

[0030] S10: Enable the caching mechanism of QGraphicsItem to improve rendering performance, and add error handling code during the parsing and display processes to ensure that when an invalid XML file or parsing error is encountered, the system can give corresponding error prompts.

[0031] S11: Implement the data export function, allowing users to export the currently displayed model as an SVG or PDF file. Add multi-language support so that the system can display the corresponding language interface according to the user's regional settings.

[0032] As Figure 1 shown, the system architecture of the present invention includes a data parsing and storage module, a table display module, a model display module, an interaction control module, and a user interface module.

[0033] The data parsing and storage module is used to parse the XML model file, extract the contact information and store it; The table display module uses QTableWidget to display the contact information and realizes the interaction with the model points; The model display module uses QGraphicsScene and QGraphicsView to display the model scene and realizes the interaction with the table; The interaction control module is used to handle the interaction events between the table and the model scene and realize the interaction effect; The user interface module is used to provide a user interface and handle user input events; The precise recognition function interface allows users to customize the selection of recognition models and adjust the parameters of recognition functions to reduce misrecognition situations.

[0034] As Figure 2 shown, the program uses C++ as the development language and QGraphicsFrameWork as the graphical framework. The program reads and displays the process of the connector model.

[0035] As Figure 3 shown, the user interface includes a QTableWidget for displaying contact information and a QGraphicsView for displaying the model scene. It includes the end face diagram interface of the electrical connector, the recognition interface, and the text detection buttons, sorting buttons, update buttons, save buttons, open output folder buttons, and close buttons in the corresponding function area.

[0036] As Figure 4 shown, the linkage interaction process includes the user selecting the contact point number in the table, the system highlighting the corresponding contact graphic item in the model scene, and the user clicking on the contact graphic item in the model scene, the system highlighting the corresponding row in the table. Users can process the recognition information of the end face diagram of the electrical connector, and then click the "Save" button to generate an XML file of the recognition result. The XML structure of the model file includes <diagram>Label and <collection>Label, wherein <collection>The label records the shape and profile outline information of the contact part, <diagram>The label records the position distribution information of the contact and the contour shape.
